Inventory of domestic compact hybrid SUV domestic hybrid has risen

[Aika car shopping guide original]

I remember when I first started as a car editor, when I talked about hybrids, in addition to Toyota and Lexus owning more than a dozen Hybird models, Honda and Acura have several hybrid models, and of course, there are "muscle-show" products like the Audi e-tron and Mercedes-Benz e-Hybrid. Other brands seem to be dismissive of the hybrid market, and are busy researching their own turbo cars. In recent years, with the increasing call for energy conservation and emission reduction, major car companies have also begun to make efforts in the field of hybrid vehicles. Chinese brands are also the first to bear the brunt of it, and the last two years are enough to be called the highlight years of Chinese independent brands in the field of hybrid vehicles. With the launch of their own hybrid and plug-in hybrid models, the hybrid car market has seen an unprecedented grand scene, and it is not too much to describe it with a hundred flowers blooming and a hundred schools of thought. Today I will take you to take a look at the success of Chinese brands in hybrid vehicles in the past two years.

The first model is the Geely Star-Vietnam L Thor Hi· X, the whole series launched a total of two configuration models, priced at 171,700 and 183,700 yuan respectively. In terms of core power technology, Hoshikoshi L Thor Hi · X adopts the DHT Pro hybrid system composed of 1.5T engine + dual motor + 3-speed hybrid transmission, not only the NEDC comprehensive fuel consumption is low value 4.3L/100km, 0-100km/h acceleration time can also run into 8 seconds, proper "Dora fast running".

Thor Hi · X uses a 1.5T hybrid engine code-named DHE15 on the conventional power unit, with 350 bar high-pressure direct injection, supercharged intercooler, low-pressure EGR technology, and miller circulation to improve fuel economy. The engine has a maximum power of 110 kW (150 hp) and a peak torque of 225 Nm.

The hybrid technology of Thor Hi-X, which probably works very similarly to Toyota's THS hybrid system, relies on the planetary gearset structure for power series parallel connection. But in fact, the DHT hybrid technology on the Thor Hi-X is still somewhat obviously different from toyota. Although its hybrid principle is still to control the series parallel connection by the clutch, the difference is that the dual motors are responsible for power generation and electric drive respectively. In this way, not only can the work efficiency be improved, but the engine can also participate in the power in two forms, both in series with the motor and direct drive.

After a brief explanation of the previous article, perhaps everyone will feel that this set of driving logic seems to be similar to Honda's i-MMD technology. It seems that this is indeed the case, but the most significant difference compared with Honda's i-MMD technology is that the third transmission combination (3 gears) designed by the Hoshigoku L Thor Hi-X on the planetary gear set can effectively improve the transmission speed domain platform of direct drive, improve the response and significantly improve the transmission efficiency.

In addition to hybrid technology, Geely Star Yue L Thor Hi · X is also unambiguous in the field of assisted driving, in addition to the basic ACC follow-up, lane keeping, parallel assist, offset warning and other functions, Geely Xingyue L Thor Hi · X is also equipped with a rich intelligent active safety system, as well as driver assistance functions that enhance the convenience of daily use.

Gilly Hoshikoshi L Thor Hi · As a HEV hybrid model, X's advantage is that it can not only save fuel consumption to the greatest extent, improve endurance, but also save most consumers from the trouble of charging FEV models and the worry of power loss and fuel saving. The NEDC cruising range of nearly 1300km also shows once again that hybrid is the development direction of fuel vehicles.

The second model is the Xingtu Wind Chasing ET-i, as a high-end brand model under Chery, the Xingtu ET-i is equipped with Chery's latest "Star Core PowerED ET-i Full Engine Super Hybrid" technology. Compared with chery's "Kunpeng DHT technology" previously launched, Star Core Power ET-i Full Engine Super Hybrid has developed an advanced plug-in hybrid technology of 3 engine, 3 gear, 9 mode and 11 speed on the basis of the Kunpeng platform. What do these numbers represent? I'll reveal it to you right away.

Engine technology has always been Chery's proudest housekeeping skill, and the 1.5T hybrid special engine used on the Xingtu Wind Chasing ET-i model has a maximum power of 115 kW (156 hp) and a peak torque of 230 Nm. Compared to the previously introduced Auspicious Star Yue L Thor Hi · X, StarWay Wind Chasing ET-i's engine power and torque are greater, and better performance means that its "bottom is better".

In addition to using a high-performance engine as a traditional drive unit, the Starway Wind Chaser ET-i is also equipped with two electric motors. The maximum power and peak torque of the P2 motor can reach 55kW and 160Nm respectively, while the maximum power and torque of the P2.5 motor can reach 70kW and 155Nm.

In terms of the logical setting of the gearbox, in the 3-speed gearbox adopted by the StarWay Wind Chasing ET-i, the 1st gear has the characteristics of a large gear ratio, which is more conducive to starting, climbing and low-speed driving, not only responding faster, but also releasing more torque. However, as the speed increases, the large gear ratio is not conducive to continuous acceleration and cruising fuel consumption when the medium and high speeds are reduced. At this time, the vehicle will switch to 2nd gear, reducing the engine cruise speed and saving fuel. The 3rd gear with the smallest gear ratio is most suitable for use during cruising, which not only keeps the speed in the most economical state, but also brings the benefit that the engine noise will also decrease with the decrease of the speed, improving the NVH performance of the whole vehicle.

In order to cope with different working conditions, the "star core power" of the StarWay Wind Chasing ET-i can also realize 9 driving modes such as pure electric driving, engine direct drive, single motor hybrid, dual motor hybrid, engine charging and parking idle charging through 3 clutches. Of course, these 9 driving modes are also to adapt to the most economical driving mode, including starting, low speed, high speed, overtaking, taxiing, congestion, uphill and other 11 life car scenes.

As a plug-in hybrid model, the Starway Wind Chasing ET-i is naturally more than the Thor Hi· X excels in pure electricity, performance and fuel consumption. In addition to the higher power engine, the dual-drive motor also makes the power response of the Star Chasing ET-i more comfortable. At the same time, the 105km pure electric endurance can fully meet the pure electric transportation needs of urban areas. With 9 different driving modes, in theory, its comprehensive cruising range can also be properly broken by 1000km.

The third model is the WEY Wei brand latte DHT, and the full guide price of the latte DHT is 15.98-17.98 million yuan. Born on the Lemon platform, WEY Latte DHT can be said to have improved its technology and efficiency on the basis of Honda i-MMD. So what are the technical similarities between the two, and what are the differences? Let's look down.

In order to cope with different road conditions and life car scenarios, Latte DHT can realize pure electric drive, engine direct drive, series driving, parallel driving and energy recovery mode through intelligent hybrid system. However, according to its drive mode and 2-speed DHT transmission, the most economical driving mode of latte DHT is not low speed and congested road conditions, but medium and high speed cruising, which can not only drive at the most economical engine speed, but also complete kinetic energy recovery at the same time.

When the latte DHT is running at low speeds, the engine is only idle or low-speed power generation even if it is running, and the wheels are all driven by electric motors. When the speed reaches the economic working speed, the engine can achieve direct drive, improve fuel economy, and reduce power transmission losses.

On a technical level, the two-speed DHT transmission adopts a parallel shaft-like layout. When the vehicle is driven by pure electrics, the electric motor is connected to the differential through the gearbox to output power. When the engine intervenes, the power will be connected to the generator through the gear set. And in the mode of the engine participating in the power drive, the two-stop torque is realized.

The WEY latte DHT takes into account the advantages of the Honda i-MMD at a technical level, and also compensates for the disadvantages of the Toyota THS system at high speed, high fuel consumption and high noise when driving at high speeds through the 2-speed DHT transmission. Of course, latte DHT and Hoshikoshi L Thor Hi · X is the same, are HEV hybrid models, in the pure electric endurance and policy does not have the advantages of PHEV models. However, if you often go out on outings and long distances, the advantages of the HEV model are gradually highlighted.

Wei brand latte DHT: high value and low fuel consumption

The fourth model is Changan UNI-K iDD, as a plug-in hybrid model, Changan UNI-K iDD adopts the current mainstream PHEV plug-in hybrid mode in the new energy market. Although in terms of technology, compared with the two-motor 3-speed gearbox plug-in hybrid technology of the StarWay Wind Chasing ET-i, the technology P2 hybrid architecture used by Changan UNI-K iDD is relatively simple and reliable, and similar technologies have also appeared in the 530Le plug-in hybrid version of the BMW 5 Series and some plug-in hybrid models under Volkswagen.

The P2 plug-and-mix architecture adopted by Changan UNI-K iDD is essentially based on the development of the fuel system, and still retains the traditional engine and gearbox. Although the battery pack with a capacity of 30.7kWh can bring 130km of pure electric endurance, the performance is not bad, and the acceleration performance is quite eye-catching. However, compared with the models in the same class that have taken the lead in using DHT transmissions, three motors and other technologies, the fuel consumption performance of Changan UNI-K iDD is not satisfactory.

Of course, the old model can still be compensated by technology, and the Blue Whale 1.5T hybrid special engine is not only equipped with 350bar in-cylinder direct injection booster, variable valve lift, and variable-section electronic turbocharging technology. At the same time, the Schaeffler intelligent electric cam variable valve timing also replaces the traditional hydraulic technology, for the intake and exhaust timing control is more accurate and fast, so as to achieve the purpose of accurate oil injection and combustion.

The 6.6kW AC fast charge can charge from 30% to 80% in about 30 minutes to meet the emergency needs of drivers. At the same time, in order to facilitate the owner of the car, improve the convenience and playability of daily use, Changan UNI-K iDD also has the function of external discharge, and the maximum discharge power of 3.3kW can also meet the electricity demand of most outdoor products.
